# NDZ Performance > NDZ Performance designs and sells custom aftermarket firearm accessories and replacement parts, with a focus on personalized, engraved components that combine visual flair with functional upgrades. Based in Cheshire, Connecticut, the company manufactures its own line of parts (slide cover plates, magwells, barrels, magazine plates, extended controls, and more) and also stocks products from established industry brands. Shoppers range from seasoned enthusiasts to weekend range-goers, and the catalog covers pistols, rifles, shotguns, holsters, optics, knives, and everyday carry gear. Orders over $69.99 ship free, and the team handles customer questions by phone at (203) 439-7784 or email at sales@ndzperformance.com. ## Frequently Asked Questions **Do I need an FFL to order from NDZ?** No. None of the items NDZ sells require an FFL to purchase. **Does NDZ offer a warranty?** All NDZ-manufactured products carry a lifetime warranty against manufacturing defects. Coatings and finishes are excluded, since those wear naturally in use (for example, a slide cycling against an installed barrel). **What is the return policy?** Returns are accepted within 30 days of the delivery date. Customers pay return shipping and a 10% restocking fee applies. To start a return, email returns@ndzperformance.com with the order number. Full terms live on the [Shipping & Returns](https://ndzperformance.com/shipping-returns/) page. **How fast do orders ship?** Orders are processed within 12 to 24 hours on business days and ship the same day or the next business day at the latest. Shipments leave Cheshire, CT via USPS, UPS, or FedEx; PO Boxes ship USPS only. Weekends and holidays are not transit days. Orders over $250 require an adult signature. **Does NDZ ship internationally?** No. Orders ship to United States addresses only. **What payment methods are accepted?** Visa, Mastercard, American Express, Discover, and Venmo. Dealers and distributors can contact sales@ndzperformance.com about ACH and other options. **Are there military or law enforcement discounts?** Yes, a 3% discount is available on phone orders for active or retired US military and law enforcement. A website-based program is in development. **Are volume discounts available?** Yes. For orders of 20 or more pieces, call (203) 439-7784 ext. 127 or email sales@ndzperformance.com. There is no minimum order quantity for regular online orders. **Can I submit a custom image for laser engraving?** Yes for orders of 10 or more pieces using the same image (contact sales@ndzperformance.com). One-off custom engravings are not yet offered but are in development. Customers who submit artwork warrant that they have the rights to use it. NDZ uses fiber lasers for etching into base materials and CO2 lasers for surface etching, and offers color fill options on certain products. Engravings are not decals or paint. **Is local pickup available?** Yes. Select "Pickup In Store" at checkout and call (203) 439-7784 ext. 127 to schedule a time at the Cheshire, CT facility. **What ammunition are NDZ barrels rated for?** Factory-new, high-quality SAAMI-spec ammunition including +P (used in moderation). NDZ barrels are not rated for +P+ / ++P overpressure loads, reloaded ammunition, or substandard components. 9mm loads exceeding 1300 FPS can cause catastrophic failure and will void the barrel warranty. **How do I become a dealer?** Submit a [dealer application](https://ndzperformance.com/dealer-application/). Once approved, dealers can place orders online while logged into the dealer account. Questions: (203) 439-7784 ext. 127 or sales@ndzperformance.com. **How do I identify which Glock generation I own?** Newer Glocks have the generation mark on the left side of the slide next to the model number. The main identifying features: - Gen 1 (1982–1988): 2-pin frame, subtle grip texture across the full grip, no finger grooves on the front strap, no thumb rest. - Gen 2 (1988–1997): 2-pin frame, subtle texture on side panels, no finger grooves, checkered front and back straps, no thumb rest. - Gen 3 (1995–2010): 3-pin frame, thumb rest, finger grooves, accessory rail. - Gen 4 (2010–present): 3-pin frame, "Gen 4" slide mark, large ambidextrous magazine release, thumb rests, interchangeable backstraps. - Gen 5 (2017–present): 2-pin frame, "Gen 5" slide mark, large ambi mag release, thumb rests, ambidextrous slide stop, flared magwell, no finger grooves. NDZ also carries parts for Glock Gen 6 and the V-Series; browse the [Gen 6 catalog](https://ndzperformance.com/pistol-glock-gen-6/) and [V-Series catalog](https://ndzperformance.com/pistol-glock-v-series/) for compatible products. **Will a Glock part listed for one model fit another?** No. If a specific Glock model or generation is not listed as compatible on the product page, the part is not designed to fit that firearm and installing it may cause damage. When in doubt, ask on the product page or email sales@ndzperformance.com before ordering. ## Main Categories - [Pistol Parts & Accessories](https://ndzperformance.com/pistol-parts-upgrades-glock-sig-1911-more-8021/): Parts for 1911, Beretta, Browning, Canik, Colt, CZ, Glock (including Gen 5, Gen 6, and V-Series), H&K, Kimber, PSA, Ruger, Sig Sauer, Smith & Wesson, Springfield Armory, Taurus, and Walther. - [Rifle Parts & Accessories](https://ndzperformance.com/rifle-parts-tools-accessories-8731/): AR-15, AR-10, AK-47/74, M1 Garand, Marlin, Remington, Ruger 10/22 and PC Carbine, Sig Sauer, S&W M&P 15-22, and Springfield M1A. - [Shotgun Parts](https://ndzperformance.com/shotgun-parts-upgrades-18467/): Benelli, Kel-Tec, Mossberg, Remington (870, 1100, 1187), and Stoeger. - [Holsters](https://ndzperformance.com/holsters-at-ndz-18522/): Holsters for Glock, Sig Sauer, Smith & Wesson, Springfield Armory, and Ruger. - [Scopes & Sights](https://ndzperformance.com/pistol-optics-gun-sights-trijicon-optics-more-9090/): AmeriGlo, Burris, Crimson Trace, EOTech, Glock OEM, Holosun, Leapers/UTG, Magpul, Night Fision, Trijicon, TruGlo, Viridian, and Zev. - [Knives](https://ndzperformance.com/custom-pocket-knives-for-edc-folding-knives-9007/): Elk Ridge, Kershaw, Masters Collection, MTech Evolution, MTech USA, Survivor, and Tac-Force. - [EDC Gear](https://ndzperformance.com/tactical-tools-survival-accessories-9135/): Flashlights, survival gear, pepper spray, apparel, keychains, patches, wallets, Zippo lighters, and automotive/powersports accessories. - [Image Library](https://ndzperformance.com/ndz-custom-stock-image-library-18571/): Browsable engraving designs used on custom parts. - [Clearance](https://ndzperformance.com/clearance/): Discounted and closeout inventory. - [New Arrivals](https://ndzperformance.com/ndz-s-new-arrival-products-18111/): Most recently released products. - [Shop by Brand](https://ndzperformance.com/shop-by-brand/): Full brand index. ## Company - [About Us](https://ndzperformance.com/about-us/) - [Contact Us](https://ndzperformance.com/contact-us/) - [FAQ](https://ndzperformance.com/faq/) - [Shipping & Returns](https://ndzperformance.com/shipping-returns/) - [Privacy Policy](https://ndzperformance.com/privacy-policy/) - [Terms & Conditions](https://ndzperformance.com/terms-conditions/) - [Patents](https://ndzperformance.com/Patents/) - [Dealer Application](https://ndzperformance.com/dealer-application/) - [Careers](https://newdesignz.com/jobs/) ## Programs & Resources - [NDZ Blog](https://blog.ndzperformance.com/) - [NDZ Insiders (early access)](https://ndzperformance.com/ndz-s-early-access-to-sales-exclusives/) - [NDZ Affiliates](https://ndzperformance.com/affiliates/) - [NDZCash Rewards](https://ndzperformance.com/how-to-earn-ndzcash/) - [Newsletter](https://ndzperformance.com/news-letter/) - [Category Index](https://ndzperformance.com/categories)
